The redesigned Terrain and its twin, the Chevrolet Equinox, bring tidier dimensions, in line with the small SUV segment. The new Terrain packs the latest infotainment and safety technology, and two four-cylinder turbocharged engines. The base engine is a 170-hp 1.5-liter, and the uplevel choice is a 252-hp 2.0-liter. Both are mated to a nine-speed automatic. A diesel engine, paired to a six-speed automatic, is also be available. GMC's IntelliLink infotainment system will be offered in 7- and 8-inch forms, each with Android Auto and Apple CarPlay compatibility.Starting with the 2020 model year, forward collision warning and low-speed automatic emergency braking, and lane keeping assistance with lane departure warning are standard on all trim lines. The 2.0-liter turbo was dropped for 2021.The Terrain is freshened for 2022 with exterior updates. It is a corporate cousin of the Chevrolet Equinox, but a few critical differences compromise it, even though it is positioned as a more premium offering. We found it to be loud and stiff-riding, with severely hampered visibility. The standard engine is a lackluster 1.5-liter turbo four-cylinder mated to a nine-speed automatic. The Terrain's gear selector is controlled by dash-mounted push buttons that are unintuitive to operate. The infotainment system is one of the easier ones to use. An off-road AT4 version is new.
